After clicking View Submission button, following error occurs.

I have tried clearing the browser cache and even flushing out OJS cache manually from server but doesn’t works.

If I open the same in an Incognito window, and after multiple hard refresh the same link with Ctrl+F5, the page opens.

I tried to search for the errors and solution in OJS forum, but could not get any clue from there.

I am using QuckSubmit plugin to add articles to OJS.

With regards,
Sharad
